it is an exotic in a way the pcar is not. from looks to layout to motor. I can see for primarily road use it is the superior machine.

yes Ive read thta, but so far we see no evidence of that. in any event, in 1 day you can do easily 50 laps and over 2 days 80-100, the question is do tires last that long, and when they are past epak say after 10 laps is it a rapid drop off from which they never recover..

Both great sports cars. I’d choose the c8 z06 over the Porsche yet keep in mind I’m obviously biased.

Tire life is going to be driver and track dependent, overheating a tire is going to shorten its life. A car with wider contact patch to weight ratio is going to have a longer life as ground psi is going to be less. A wider tire is going to have more thermal capacity and take longer to over heat all else equal. 2 cars running the same lap time and one heavier than the other is generating more heat in the engine, brakes etc especially given the min/max speed most likely have a higher delta…many variables to consider and wouldn’t make a blanket statement

Nice! I'd love to take that and a GT4 RS Clubsport out for a few sessions for some comparisons.

There is a GT4RS allocation available from a broker over on Rennlist. 65k over MSRP. Seems to be the going rate.

I agree with the overall premise of your post, however this number stuck out at me. The article in question says "some 450 lbs", yet you're saying 5-600 lbs. MT's numbers at the end of the article put it at 454 (3686-3232), but it's not specified if they're quoting mfg numbers or using their own measurements. 450 lbs is still a lot (although the C8 is a larger, more road focused car), but 5-600 might be an exaggeration here.

Originally Posted by AzDave47

In fact, the Z06's figure-eight time was so good, it briefly held Motor Trend's record time—until it was beaten that same day by a half-million-dollar McLaren 765LT Spider.

At least in prior reports they acknowledged how great the figure 8 number was. Here, it LUMBERS away? A car doesn't turn great times on the figure 8 test by lumbering. I guess I will send another letter to MT when the print version comes out.
So I read that as that it was lumbering away from the GT4RS as it was slowly pulling out a lead. Lumbering does have a bit more of an awkward connotation to it, so I agree it's not a great choice of words, but I read it as their intent was to say that it was slowly but surely pulling ahead of the GT4, not that it was slow or awkward around the course itself. YMMV.

I know, like with the C8, there are ways to get MSRP. But in general being a car person is getting way less fun.
-Lack of interesting models
-Push for soulless EVs
-Many new models look way uglier than previous (looking at you Mercedes, Audi, BMW)
-ADM BS

I agree, and the camaro at 4000lbs could certainly hack it. But the 1 le was also a very focussed car. I'm juts saying so far we have no evidence of the z06 beyond it can run a quick lap or two on fresh rubber, the same could be said of a c7 z06 and zr1. What any serious track junkie would like to know is consumables at full tilt over 2 days, cause thats real use. magazine tests they way theyre done, that for baroom bragging, and yes displays potential, but not actual track use.On a Gt3 its now a know quantity, and more or less the same for the 4rs, 2k per day when all is said and done. If a z06 eats $2500 worth of tires in less than two days, not to mention pads and rotors, thats very different. Speed Phenom indicated his maclren 6000lt was for that reason less to run on track than the z06. in any event regardless of cost, if tires cant last two days, the use cycle of a z06 is seriously limited.

yeah soulless Evs.
Look at what cars are hard to get.
Honda CTR, Toyota GR carolla, Audi RS4 Vettes, Gt series proche.
manufacturers are trying to push what people have enough of, and are not building enough of what more than a few want.,
the car gearhead community is far larger than manufacturer clinics indicate. Wer'e the ones whop buy premium profitable products. The rest buy badges or appliances.
However small that gearhead community is, its still something like 200k+ units in the uSa per year. (v8 mustangs, challengers, vettes, CTR Audi porche Gts, cadillac blackwing etc)
Hell it turns out even the demise of the stick shift was greatly misunderstood by the corp types, its now a sporty premium product. Turns out in a sea of sameness more than a few people want cool looking fun engaging cars.
Time to crank up those production line and fire the product planners who limit production of cool cars cause theye dont get it..

The mooted electric dodge charger may be the first interesting electric car from a fun perspective, and that still remains to be seen.

The GT4RS is a monster on a track, but not really usable on the street. It is loud as hell and with the carbon race buckets super uncomfortable. I just sold mine. Love the way it looked...

Apart from the ADM, youre also forced into buying a car loaded with 50k worth of crap.


I was at the toyota dealer to have my tundra serviced, saw a Gr corolla in the showroom. car listed for 38k and there was a 20k dealer adm. Its a cool niche car for 38k, you'd have to be an idiot to pay 60k for it. My bet is it will sit for long time, just as delaers ended up stuck with focus rs back in the day.

Dont know whether you'll ever be able to get the Rs at msrp. but the vz06 will surely get there, and honda CTRs are there already if you look. I thought porche was a profit making business, cayman production is not limited, so why they dont make more Gt4rs, probably because porsche usa is controlled by MBA's marketers and overy influenced by dealers and dealers for obvious reasons would rather sell 4 cars with a 65K adm than 15 cars at list.

Much as I think Musk is part charlatan, his no dealer gives him a lot of fexibility to satisfy the market, and I'm a guy who in general does not have an issue going to a dealer, but seriously these days they have proven themselvs as a group on average to suck. You cant create brands, create sustainable customer bases if you're also fleecing at the first and every possibility.

Its really meant for the track though, and certain weekend drives. Useable is a Gt4 or a 911 Gts.

Their figure 8 event is only 22 seconds long for the quick cars so everything happens quickly. Since the C8Z was one of only 2 cars to ever break 22 seconds, Lumbering was a very derogatory description of its performance.

Some cars are sledgehammers others more like rapiers. Lumbering to me implies a big car, with wide wide tires and lots of power, not fully settled, bludgeoning its way out a corner.

SERIOUSLY……..PORSCHE is they Worlds 1 and ONLY manufacturer that designs and engineers cars that can WIN on SUNDAY and sell on MONDAY to the public.

Your GT4RS build was my initial spec BUT I went for PTS .

COME-ON the Carbon buckets re 100% comfortable and its sounds great …………it’s an expensive daily driver. The worse riding car I ever owned was a 1984 Corvette C4 Z51……rode like a buck-board slow as hell unreliable and electrical gremlins. IM DOWN for a C8 Z06. It’s finally the real deal. Currently harder to obtain ……..why? 5 whys ? Make 1500 C8Z06 cars per year for 5 years ……….keep it unique and rare . JERRY VETTE I'll get you a GT4RS …..try it change your handle .

Who would rather own a C8 Z51 versus a lousy PORCH 992 GT3 or GT4 or GT4RS ?


another lousy VW AUDI Porsche product and a lousy FIAT product in the back ground ………what’a POS ……..its a manual 6 speed



1987 Porsche 930 TURBO S 500 horsepower 4 speed 2800 pounds 4 speed Ltd slip ……NO power steering NO ABS brakes, NO Navigation, NO Airbags , NO satellite uplink, no heated A/C seats , …………TURBO lag ……slow throttle response ……WON LEMANS 1979 outright ………better than a 992 GT3RS or C8Z06 Z07? What was I thinking bought for $28,000 in 2008 credit crisis ………worth $300,000 ……no apple car plays no voice commands no no NO ….send it to the CRUSHER …….trade for a high mileage beat up 1987 C5 ?

Der widow-maker ………ya ya………… I hate anything BUT Chevies . KEEP an OPEN mind all cool cars are wonder ful………C8Z06 is like the space shuttle !!

C8 Z51 isn’t a fair comparison to GT3 or GT4RS. I’d say it compares to the 992 S or GTS as far as performance, but those are in the price point of a C8Z06 so who would choose one of those over a C8Z06?
